Merge of r4920, r4939: ngx_write_chain_to_file() fixes.
*) Core: added debug logging of writev() in ngx_write_chain_to_file().
*) Core: fixed ngx_write_chain_to_file() with IOV_MAX reached.
Catched by dav_chunked.t on Solaris. In released versions this might
potentially result in corruption of complex protocol responses if they
were written to disk and there were more distinct buffers than IOV_MAX
in a single write.
